The safety of surgical technique for ileostomy and colostomy in preventing parastomal hernias: an in vitro experimental simulation study

Background Parastomal hernia (PH) is a common long-term complication in persons with an ostomy. Although the cause of PH may be multifactorial, the surgical technique employed for the creation of a stoma may be a risk factor for the development of PH. The traditional technique of cruciate fascia incision may predispose to increased pressure zones at the ostomy exit site, thereby increasing the risk of PH. A circular excision of the abdominal fascia at the ostomy exit site enables a uniform pressure distribution, thereby reducing the risk of PH. This hypothesis was tested in this in vitro experimental simulation study. Methods The effect of the surgical technique for ostomy creation on the risk of PH development was investigated in this in vitro experimental simulation study. The pressure development at the stoma site was compared for the traditional cruciate incision vs. circular fascia excision. Results The pressure at the ostomy site was about four-times higher in the tradition cruciate incision technique compared to the circular excision technique. This finding was independent of unilateral (e.g. peritoneal) pressure application. Conclusion The main finding from this study suggests that the traditional cruciate incision of the abdominal fascia for the creation of an intestinal ostomy predisposes to increased pressures at the ostomy site, thus increasing the risk of PH. This effect is not seen in the experimental setting following a circular excision of the fascia. Thus, this surgical aspect may be adopted as a possible means of reducing the risk of parastomal hernia in patients undergoing ostomy surgery.

One of the rare reason of abdominal pain: abdominal wall endometriosis

Objective: Endometriosis is defined as the presence of normal endometrial mucosa abnormally implanted in locations other than the uterine cavity. It is most commonly located in the pelvis but it is also rarely observed in the gastrointestinal tract, lung, liver, kidneys, central nervous system and abdominal wall. Abdominal wall endometriosis (AWE) commonly occurs following a caesarean section or pelvic surgery. The patients consult the physician mostly with complaints of cyclic abdominal pain and a palpable mass in the abdomen. The basic methods in diagnosing AWE are anamnesis and physical examination but ultrasound, computerized tomography, and sometimes magnetic resonance imaging of the abdomen are also used. Material and Methods: In our study, we retrospectively analyzed 9 patients who underwent surgery at Avcılar State Hospital General Surgery Service between January 2015 and December 2018 with a preliminary diagnosis of AWE and confirmation through pathology results. Results: Median age of the patients was 32 ± 4.66 and median body mass index (BMI) was 24.6 ± 1.15. Every patient except 1 had a history of cesarean section history. One patient was operated because of recurrence. Patients consulted the hospital with complaints of pain during menstruation and abdominal swelling. The start of the complaints was 4.1 years following C-section. Mostly ultrasound was used for imaging. For treatment, they all received en-bloc mass excision and their pathological diagnosis were compliant with endometriosis. Average surgery time was 40 minutes and average endometriosis lesion dimension was 3.4 cm. It was observed that the lesion extended to the anterior abdominal fascia in 6 of the patients, and 2 patients underwent fascia repair with propylene mesh because of the excessive defect size. No postoperative complication occured in any patient and no recurrence is observed. Conclusion: In patients with periodic abdominal pain and swelling on the abdominal wall, AWE could be suspected and early diagnosis can be realized by carefully taking medical history and following physical examination, and appropriate radiological examinations and necessary surgical intervention can be performed. The method of diagnosis and treatment is to remove the lesion through wide excision.

The impact of different suturing techniques for abdominal fascia closure on the Interleukin-6 expressions in Rattus norvegicus

Objective Incisional hernia is a frequent complication of midline laparotomy. The suturing technique is an important determinant of the risk of developing an incisional hernia. Moreover, IL-6 has crucial roles in the wound-healing process. We aimed to compare the large stitch vs. small stitch technique for abdominal fascial closure on IL-6 expressions in rats. Results Twenty rats were used. The small stitch group received small tissue bites of 5 mm and the large stitch group received large bites of 10 mm. The incisions of fascia were closed by running sutures. Animals were euthanized on days 4 and 7. Histological sections of the tissue-embedded sutures were analyzed for IL-6 expressions. Two-way ANOVA showed that rats in the small stitch group had similar IL-6 expressions on days 4 and 7 to those in the large stitch group (p = 0.36). In conclusion, the IL-6 expressions are similar between the small and the large stitch groups, implying that different suturing techniques might not have an impact on the incisional hernia occurrence.

Comparison of continuous versus interrupted abdominal fascia closure using polydioxanone suture in laparotomy

Background: Laparotomy is a major surgical procedure in emergency settings. There is paucity of data regarding abdominal fascia closure in emergency laparotomies in Indian population. This study was planned to compare two techniques of fascial closure namely continuous and interrupted using polydioxanone in patients undergoing midline emergency laparotomies in our institute.Methods: This prospective study was conducted in Surgery Department, MMC&H, Muzaffarnagar, from January 2017 to June 2018. 60 patients undergoing emergency laparotomies were divided into two groups of 30 each. Group I (study group) patients underwent interrupted suture abdominal closure; Group II (control group) patients underwent continuous suture closure.Results: Commonest diagnoses were duodenal and enteric perforations. Mean closure time in Group 1 was 31.6 minutes and in Group 2 -17.3 minutes. Mean hospital stay in Group I and II were 12.88 and13.76 days respectively. 4 Group I patients developed wound discharge versus 6 patients in Group II. Burst abdomen occurred in 3 out of 60 patients. One Group I patient had localised fascial burst. One Group II patient had localized while one had complete fascial burst. One incisional hernia was observed in each group at 3rd month of follow up. Three patients in Group 1 and one in Group 2 developed suture sinus.Conclusions: Major complication is wound dehiscence leading to increased morbidity, hospital stay and cost. In our study, we used continuous and interrupted PDS sutures and found that interrupted suturing method of abdominal wall closure is better, though it takes more time.

Giant Gastroschisis with Complete Liver Herniation: A Case Report of Two Patients

Introduction. There are no reported survivors of gastroschisis with complete liver herniation. We describe a case report of two patients, one of whom survived. Case #1. The patient was born with gastroschisis and herniation of the entire liver. Along with silo placement, the abdominal fascia was attached to an external traction system for growth. Complete closure was achieved at 5 months. Due to pulmonary hypoplasia, high-frequency ventilation was required. The patient is doing well, on a home ventilator wean, at 20 months. Case #2. The patient was born prematurely with gastroschisis, total liver herniation, and a defect extending to the pericardium. A silo was attached to the fascia to provide growth of the abdominal cavity. The patient developed respiratory failure, diffuse anasarca, and renal failure. She died at 38 days of life. Discussion. We report the first survivor of gastroschisis with complete liver herniation, contrasting it with a death of a similar case. The associated pulmonary hypoplasia may require long-term ventilation, the inflammatory response can lead to anasarca, and renal injury can occur from acute-on-chronic compartment syndrome. Conclusion. External fascial traction systems can help induce growth of the abdominal wall, allowing closure of the challenging abdomen. While critical care management is complex, survival is possible.

Interrupted Midline Fascial Closure to Prevent Burst Abdomen in Emergency Laparotomy: Comparison between Continuous and Interrupted closure

Burst abdomen represents one of the most frustrating and difficult postoperative complication that concerns every abdominal surgeon. It occurs because of various predisposing factors which can be prevented to some extend by having knowledge regarding them. Despite many years of experience, the optimal technique of laparotomy closure remains controversial. The varieties of surgical excess as well as the varieties of abdominal closure techniques are the main difficulties in the proper standardization of this procedure. In this paper a randomized prospective study was designed to compare with a interrupted and continuous technique for closing a midline abdominal fascia in emergency laparotomy. A total of 300 patients of acute abdominal condition who underwent laparotomy were randomized into two groups of 150 patients in each group. Total 22(7.33%) of 300 patients developed burst in the postoperative period. Fourteen (14) (9.33%) in continuous arms and eight (08) (5.33%) patients in interrupted arms developed burst. Burst abdomen occurring mostly 40-60 years age group with a male to female ratio of 1.68: 1. Cough, anemia, malnutrition, DM, intraperitoneal sepsis, wound infection, uremia and abdominal distension were the important predisposing factors for the incidence of burst abdomen. Interrupted suturing was associated with significantly reduced the burst abdomen when comparing with continuous closure.TAJ 2017; 30(2): 69-75
